Brocade VDX switches are designed to help organizations stay ahead of application-driven network change by enabling agile growth through a scale-out architecture. This approach offers three key benefits. First, it enables network expansion as a business grows over time. One can horizontally scale spine switches as the number of leaf switches increase. Second, scale-out architecture also enables the creation of resilient network fabrics, eliminating a single point of failure and potential downtime. Third, and most important, a scale-out network architecture delivers a compelling economic benefit. Unlike scale-up, a scale-out model lowers upfront investment. And by using high-density fixed switches, it lowers the Total Cost of Ownership (TCO), reducing power, cooling, and data center space.
